Clinical trials reported a potential synergistic effect of sunitinib in combination to rapalogs in some advanced cancers.
Several VEGF pathway inhibitors have shown clinical activity in NENs.
Sunitinib exhibits a weak cytotoxic activity due to its inhibitory effect on VEGFR2 signalling.
Inhibition of Akt/mTOR signalling sensitises resistant cancer cells to treatment with sunitinib.
We discuss the role of dual blockade of VEGF and mTOR pathway, focusing on current studies and future perspectives.
